Spiral Submerged Arc Welded Pipe - jundesteelpipe

Spiral steel pipe, also called spiral steel tube or spiral welded tube, is a method in which a low carbon structural steel or a low alloy structural steel strip is rolled into a tube blank at a certain angle of a helix (called a forming angle), and then the tube seam is welded. It can produce large diameter steel pipes with narrow strips.

Using Cameras When Welding Spiral Pipe Processing and Tacking

Aug 16, 2017 · Helical (or Spiral) Submerged Arc Welding (HSAW) allows for larger, thinner-wall welded pipe, but this benefit has a cost—a higher chance of welding defects. By enabling greater visibility and control during processing and tacking, high dynamic range (HDR) weld cameras are a powerful tool to counter this risk. The Advantages of HSAW

What is The Differences Between LSAW Pipe and SSAW Pipe

It is using the same welding technology of Submerged Arc-Welding with LSAW pipe. Differently SSAW pipe is spiral welded where the LSAW is longitudinally welded. Manufacturing process is rolling the steel strip, to make the rolling direction have an angle with the direction of the pipe center, forming and welding, so the welding seam is in a ...
